[technical field]

The relevant a kind of electric connector of the utility model refers to a kind of micro coaxial cable connector assembly especially.

[background technology]

Utilize cable ends connector and cable termination and electrically connect realizing that transmission manner becomes a kind of known technology to signal already between the two with butt connector, most of micro coaxial cable connector assemblies break away to avoid the two by interlock mutually with corresponding butt connector.

The U.S. the 5th, 788,534,5,820,412,4,961,711,5,009,616,5,011,424 and 5,124, No. 506 patent has disclosed the micro coaxial cable connector assembly that has in order to the locked instrument of fixing butt connector respectively.

Yet, be accompanied by the development of electronic industry, in the industry electric connector has been produced stricter requirement.Described all locked instruments can't satisfy the demand that novel electric connector uses down at poor environment (as the high vibration environment).

Therefore, industry need a kind ofly connect the locked instrument that more reliable confining force and handled easily are provided between the electric connector at two now.

In sum, necessary design is a kind of has the micro coaxial cable connector assembly of modified form locked instrument to overcome defective of the prior art.

[summary of the invention]

The purpose of this utility model is to provide a kind of micro coaxial cable connector assembly, and its locked instrument is operated easily and can firmly be connected this micro coaxial cable connector assembly and butt connector.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of micro coaxial cable connector assembly, and it comprises insulating body, plurality of conductive terminals, first lid, second lid and pair of fastening, described conducting terminal is installed on the insulating body; Described first lid contains insulating body in it and have an a pair of conduit; Described second lid is assembled in first lid, and it has pair of flanges, the common formation of each flange and corresponding conduit one passage, and this passage has the joint portion; Described tightening member is retained in the described passage and can moves within it, each tightening member comprises pars intermedia, extends and head that forms and the transition part that extends to form with respect to the head rightabout from pars intermedia court from pars intermedia, the joint portion of described transition part and first, second lid all has tapered forward taper configurations, and this transition part matches with described joint portion.

Compared with prior art, the utility model micro coaxial cable connector assembly has the following advantages: because the transition part and first of tightening member, the joint portion of second lid all has tapered forward taper configurations, when the complete precession butt connector of the head of tightening member and with it in conjunction with the time, first, second lid applies direction active force backwards to transition part, like this, can reach very firm threaded engagement between head and the butt connector, thereby under high vibration, described threaded engagement between micro coaxial cable connector assembly and the butt connector also is difficult for lax, therefore, micro coaxial cable connector assembly can be reached very reliable and firm locking with butt connector by described tightening member and cooperates.
